Professional Applications & Engineering Value

Engineered for demanding industrial settings, these black-oxide steel flat washers provide critical protection against galvanic corrosion and surface abrasion. The precise 1.031" inner diameter and 2" outer diameter ensure optimal alignment with 1" screw sizes, distributing clamp load evenly to prevent joint loosening under vibration or dynamic stresses. With a thickness range of 0.230-0.255", they maintain structural integrity in heavy machinery, construction assemblies, and automotive systems, reducing maintenance downtime. The black-oxide coating extends service life in humid or chemically exposed environments, making them a cost-effective solution for OEMs and MRO professionals seeking durable, compliant components.

Specification Summary & Compliance

This flat washer adheres to inch-system dimensional standards with an ID of 1.031", OD of 2", and thickness tolerance of 0.230-0.255". Manufactured from black-oxide steel, it is compliant with RoHS 3 (2015/863/EU) under exemption 6(a) for lead in steel alloys and REACH (EC 1907/2006) for hazardous substances, ensuring regulatory alignment for global industrial use.
